18 Claims.

My invention relates to sealing means for doors, hatches or other closures and it has for its principal object the provision of means for rendering doors and the like Water-tight. gas-tight, and weather-tight as well as flame tight.

The present application is a division of Amy copending application Serial No. 153,221, filed July 12, 1937, now Patent No. 2,140,570, of December 20, 1938, the latter application being a continuation in part of my application Serial No. 123,500, filed February 1, 1937.

The primary feature of the invention consists in providing a door or the like with a strip of relatively exible sealing material and with a rigid member interposed between the strip and the door, and in having means surrounding the opening to be closed by the door which is adapted to 'be in such contiguous relation with said rigid member when the door is closed as to prevent the passage of flames from one side of the door to the other and which is also adapted to press the sealing strip against the rigid member.

Another feature of the invention consists in providing La door or the like with a relatively flexible strip of sealing material and with a rigid member overlapping the inner face ofy the strip which is provided with a portion offset rearwardly from the strip, means surrounding the opening to be closed by the door being provided to deflect a portion of the sealing strip rearwardly as the door is being moved toward closed position and for compressing the portion of the strip against the offset portion of the rigid member when the door is fully closed.

A further feature of the inventionresides in providing the inner face of the door with a relatively exible sealing strip and with a plate-like member overlapping the innerl face of the strip and having a portion offset rearwardly therefrom, means surrounding the opening to be closed by the door being arranged fso as to be contiguous to the plate member when the door is closed and to also deecta portion of the sealingstrip rearwardly when the door is being closed and to compress the strip against the oiset portion of the plate member when the door is fully closed.

Other and more specific features of the invention residing in advantageous forms, combinations and relations of parts, will hereinafter appear and be pointed out inthe claims.

y In the drawing, wherein the invention isshown as applied to a bulkhead of a ship,

Figure 1 isan elevational view of the inner face of the door and adjacent portions'of a bulkhead.

Figure 2 is a detail sectional view taken on line 2-2 of Figure 1.

Figure 3 is a fragmentary sectional view of adjacent portions of the door and bulkhead illustrating the door in a partially closed position.

Figure 4 is a view corresponding to Figure 3 illustrating the door in fully closed position.

Figure 5 is a view similar to Figure 4 illustrating a modified form of the invention.

Figure 6 is another view similar to Figure 4 illustrating another modified form of the invention.

Figure 7 is a fragmentary sectional view taken on line 1-1 of Figure 1.

While the invention has been illustrated as applied to a bulkhead and its associated door, it will be apparent that it is not limited in its application to doors of this type but, on the contrary, is capable of application to substantially all types of closures generally. zo Referring more particularly to the drawing, I

v-edges thereof and are respectively provided with 30 a plurality of hooks or shouldered members 4 for cooperating with brackets 5 rigidly secured to the bulkhead. Pivotally mounted upon the door intermediate the shafts 3 is a lever E having eccentricslots 1 for receiving pins 8 which project laterally from links 9 pivotally connected at their outer ends to arms i0 with which the shafts 3 vare respectively rigidly provided. It will thus be seen that rotation of the lever 6 will impart move- Y ment to the shafts 3 so as to cause the hooks 4 to move relatively to their respectively cooperating brackets 5.

The door securing mechanism may also include two pairs of auxiliary shafts Il which are respectively mounted adjacent the top and bottom edges of the door, each of the shafts being provided with a hook l2 for cooperating withan adjacent bracket I3. Motion may be imparted to the auxiliary shafts from the main shafts 3 through the intermediacy of suitable gearing.

The sealing means which forms the subjectmatter of the present application includes a relf atively exible strip of sealing material I4 which is disposed on the inner face of the door andextends longitudinally along each of the edges thereof. The sealing strip may be of any suitable material, such, for example, as rubber, and it projects inwardly from inturned or rearwardly projecting marginal anges I5 with which the door may be advantageously provided.

Rigidly secured to the flanges of the door by any suitable means, such as by welding, are laterally spaced members I 6 and I1, respectively, between which the sealing strip is adapted to be inserted for connection to the door. Member I6 may advantageously be in the form of an angle, one leg I8 of which is secured to the adjacent marginal ange of the door and the other leg I9 of which overlaps the outer face of the strip adjacentits inner edge. The member I1 is disposed rearwardly of the sealing strip and may be conveniently of plate-like formhaving an inner portion 20 adapted to overlappingly engage a portion of the rear face of the strip and an outer portion 2I which is offset rearwardly from the portion of the strip adjacent its inner edge so as to be normally disposed in spaced relation thereto.

While the space between the leg I9 of angle member I6 and the inner portion 20 of plate member I1 may be only slightly narrower than the thickness of the sealing strip so that by compressing the latter it may be inserted within the space and thus be rmly held in position, it is preferred to make the space sufilciently wide to accommodate ller plates 22 as well as the sealing strip. By employing filler plates of varying thickness, sealing strips of varying thickness may likewise be employed. Suitable cement or other supplementary means may be used, if desired, in securing the sealing strip in position.

To maintain the ller plates in place, they are each provided with one or more elongated openings to receive the inner ends of screws 23 which `are screw threaded in leg I9 of angle member IE,

While the screws may engage the sealing strip to retain it in place, this has been found unnecessary, if, as is preferred. ller plates of suincient thickness are employed that the portion of the strip engaged thereby is maintained under compression. The sealing strip is preferably inserted between members I6 and I1 before the nller plates are inserted, and in order that the plates may be easily pushed or driven in place and at the same time subject the strip to compression, the inner corners of the plates adjacent their rear faces may be suitably rounded, as indicated.

Surrounding the opening in the bulkhead is an outwardly extending flange 24 which, when the door is closed, is adapted to be so contiguous with and yet not necessarily engage the inner portion of plate I1 that flames cannot pass from one side of the door to the other and that names originating on the inside of the door cannot reach and thus destroy the sealing strip. In all forms of the invention illustrated in the drawing, with the exception of Figure 6, the flange 24 is adapted to overlap and be contiguous with the inner edge of the offset portion 2| of the plate member and in order that the outer edge of the ange may pass beyond the plate member I1 and thus not interfere with proper closure of the door, the outer end portion of the flange is beveled or inclined,

as indicated at 25, so that, as the door approaches closed position, the incline or bevel of the ange will serve to properly position or center the door with respect to the opening, the door being enabled to shift laterally or adjust itself slightly by having the openings in the hinge butts 26 ofy the door of somewhat greater diameter than the pins 21 which hingedly connect the door to brackets lorov Rigid with the flange 24 and having a portion `spaced laterally therefrom is a member 29 which is adapted to coact with the sealing strip. As shown in Figure 3 of the drawing, member 29 is adapted to engage the outer portion of the sealing strip and deflect it rearwardly as the door approaches closed position and, as shown in Figure 4, it is so arranged that, when the door is fully closed, it firmly compresses the outer portion of thesealing strip against the oii'set portion 2| of the. plate member I1. The sealing effect which is thus produced is not only obtained by maintaining the strip under compression but it is also obtained by reason of the strip being deflected rearwardly. In the event, therefore, it should become impossible to subject the sealing strip to the desired compression by reason of the door having become distorted or deformed, or for other reasons, the sealing effect a laterally projecting ange 30, as shown in Figure 5, which is adapted to bridge the space between the portion of member 29 which engages the sealing strip and the outer edge of legI9 of the angle member I6. By thus providing member 29 with a portion whose outer edge is disposed contiguous to the outer edge of leg lI9 when the door is closed, the exposed outer surface of the sealing strip will be substantially entirely covered and names from ilre which may occur on the outside of the door will tbe prevented from reaching the sealing strip.

Instead of having the flange surroundingthe door opening project beyond the inner edges of plate member I1, as in the preferred form of the.

invention,the plate member may be of greater width, as indicated at 3| in Figure 6, so as to provide an abutment for the inner edge of the `iange surrounding the door opening. In this embodiment of the invention, the flange surrounding the door opening is, of course, of less depth than in the forms of the invention illustrated in the other figures of the drawing but the sealing strip will be as effectively protected from names on the inside of the door and member 29, `which is rigid with the flange, cooperates with the sealing strip in the manner heretofore described.

From the foregoing, it will be perceived that a sealingv meansis provided whichis capable of effectively rendering a closure water-tight, gastight, and weather-tight, as well 'as name tight, and which may be applied to practically every type of closure irrespective of the character of securing mechanism with which itv may be equipped. Itis, of course. manifest that various modiiications and rearrangements of lthe parts of the specific structures illustrated and described may be made without departing from the spirit and scope of the invention as defined in the appended claims.
